PROBLEM TO BE SOLVED: To provide a reduction gear with a large diameter output shaft which is a frame rotary type and which can stably support the output shaft without enlarging the axial length of the whole reduction gear. SOLUTION: In the reduction gear with an internal gear 58 (a ring member) performing power transmission in its own inner periphery side as one component of a planetary reduction mechanism 50, a pulley body 62A (a rotary ring) is arranged in the radial outside of the internal gear 58, and a sliding bearing 59 is arranged between the pulley body 62A and the internal gear 58 (and its extended portion).
